No matter what it is, after a long time of use, it is inevitable that the phenomenon of damage will occur. The water ring vacuum pump manufacturers are widely used in many industrial fields. How can the water ring vacuum pump manufacturers be broken? What are the maintenance methods of water ring vacuum pump manufacturer? Today, I'd like to take you to learn about the maintenance of the water ring vacuum pump manufacturer.

Problem 1: oil leakage of water ring vacuum pump manufacturer

A: oil leakage is one of the most common failures of rotary vane water ring vacuum pump manufacturers. It mainly occurs in the oil window, oil tank gasket and motor bearing shaft seal of the water ring vacuum pump manufacturer. The main reason is the aging of these parts caused by the long service time of the water ring vacuum pump manufacturer. Seal failure, resulting in oil leakage.

Solution: replace the aged oil window, shaft seal, gasket and felt pad full of oil after maintenance. Before oil injection, the manufacturer of water ring vacuum pump should be washed with oil from the manufacturer of water ring vacuum pump, and the filter screen at the oil injection port should be cleaned with solvent to keep the oil tank clean.

Problem 2: the manufacturer of the water ring vacuum pump can not be started (mainly because the manufacturer of the water ring vacuum pump can not start normally after being powered on)

Solution: first of all, check whether there is a problem with the circuit of the water ring vacuum pump manufacturer. For example, whether the safety tube is burnt out or not, and whether the circuit part is burnt out. After troubleshooting the circuit part, two other factors should be considered

1. Motor burn out: it is mainly caused by the burning of motor stator coil, which is caused by many reasons. For example, the instantaneous current is too large and the motor bearing has been worn for a long time, resulting in the bearing friction resistance increasing, motor power increasing, causing temperature rise and motor burning. At this time, the motor coil should be checked first. If the bearing is damaged, replace the bearing; if the motor coil is burned, repair the motor and rewind the sub coil. If the bearing and coil are damaged seriously, a new motor must be replaced.

2. Rotor jamming: the main reason is that the friction resistance between the vane and the pump cavity surface is too large, which makes the motor unable to drive the rotor. The reason is that the vane is deformed, the spring in the rotor can not be reset after opening, or the resultant force of spring pressure and centrifugal force of the vane itself is too large, resulting in the friction resistance between the vane and the surface of the pump cavity. At this time, it is necessary to repair the rotating blade and spring in time. If it cannot be repaired, it will be replaced.

Problem 3: the limit vacuum degree of water ring vacuum pump manufacturer cannot be reached

Solution: first check the tightness of the vacuum system to see if there is air leakage. Then open the gas valve of the water ring vacuum pump manufacturer and let the water ring vacuum pump manufacturer run for about half an hour. To drain the compressible steam which is not caused by pump oil pollution of water ring vacuum pump manufacturer, and eliminate the influence of compressible steam on the limit vacuum degree.

After eliminating the above two factors, the other reasons are as follows: the oil pollution of the water ring vacuum pump manufacturer needs to be replaced; the filter blockage in the water ring vacuum pump manufacturer causes the oil circuit of the oil injection system is not smooth and the oil supply is insufficient, resulting in the pump body sealing is not tight, so it is necessary to clean the internal oil filter; deformation, wear or damage of the oil distributor valve may also lead to insufficient oil supply At this time, the valve of oil distributor should be checked and replaced; if it is used for a long time, the vane of the water ring vacuum pump manufacturer is worn or the spring tension in the rotor is insufficient, which leads to the poor isolation between the suction port and the exhaust port, resulting in the decline of the vacuum pumping performance of the water ring vacuum pump manufacturer. And clean the rotor and pump chamber; check the exhaust valve to see if its action fails, resulting in poor exhaust, and replace the exhaust valve if necessary.
